ADT^A14 — Pending Admit

Bed pre-reservation: the admission is confirmed but the patient has not yet physically arrived. A14 warns downstream systems of the upcoming occupancy.

Purpose

A14 broadcasts that a patient will be admitted within a short horizon (hours to days). It is used to block a bed under preparation, alert the receiving unit (kit prep, staff planning), warn the LIS to pre-create the admission record, and let the pharmacy forecast supplies. A14 shares the abstract structure ADT_A05 with A05 (Pre-Admit), A28 and A31.

A14 is not a firm admission: A01 seals the patient's actual arrival. The A14 → A01 transition is typically correlated via PV1-19 (visit number), which must stay stable.

Segment structure

Structure ADT_A05 identical to A05/A28/A31 — PV1 mandatory with a planned date.

PV1 — planned visit

• PV1-2: class — often P (Preadmit) on A14, becomes I on A01.
• PV1-3: reserved location (pre-assigned bed).
• PV1-19: visit number — stable technical key between A14 and A01.
• PV1-44: planned admission timestamp (CCYYMMDDHHMMSS).

Real-world example

A14 issued on 16 May 2026 at 08:15 for an admission scheduled for 20 May at 14:00:

Common errors

• PV1-19 differs between A14 and A01: breaks correlation; the receiver creates two distinct visits.
• PV1-44 missing: the planned admission has no date — the EHR cannot plan.
• A14 without A27 (Cancel Pending Admit) on cancellation: leaves a ghost bed reserved indefinitely.
